Is there a way of sending different frequency values to the same oscillator by dedicated triggers ( for example: !trig1 100hz; !trig2 400hz; and so on ...)?. Not arrays? Or simpler?

Many thanks

Maybe one way to do it is with a fader that selects from an array. You could put labels on the fader by unlocking the VCSEditor, double click fader, under Options select Set tic marks and labels.

((!Fader * 4) of: #(200 500 800)) hz

Many thanks for your answer. I am creating a patch that makes telephone dial tones where each trigger works as the telephone keyboard (each key number has its own frequency associated). When no trigger the objective is silence.

!Key1 true: 697 false: (!Key2 true: 1336 false: (!Key3 true: 1477 false: (!Key4 true: 1633 false: 0)))

and in the Envelope field, something like the OR of all the Keys, so:

!Key1 + !Key2 + !Key3 + !Key4

where you would add more keys and more cases to the expressions.

Many thanks for your answer. It worked (of course it´s Kyma!!)
I am transcribing to Kyma the examples programmed in Pure Data found in the book "Designing Sound" by Andy Farnell. As I teach Sound Design in a high school I wanted to use this examples to show students how to create sounds from the scratch using synthesis techniques. I am developing the other examples and I will post them as I am programming. It will be divided in classes of sounds (artificial, sci fi, nature, and so on).
So if you don´t mind I will be posting some doubts along the way ;-)

A simple question has (probably) a simpler answer. I am using a sine oscillator that has an amplitude envelope controlled by a 2 Hz LFO square wave. The problem is that the sound is always clicking ... How can I round the shape of the square wave so it does not click?

Thanks for your answer. I tried already with smooth square but it clicks anyway... With sine wave it´s okay but as I am designing some alarm sounds the osc freq should be ruled by a squareLFO.

A little known fact: the predecessor to the Platypus (which is the predecessor to the first Capybara) was a Blue Box developed by Sherwin Gooch at the CERL Sound Group at the University of Illinois. A blue box was a tone generator that could be used to fake out the telephone network allowing you to make free long distance calls. Rumor has it that Sherwin once managed to make a connection from Urbana through Australia, back to another phone in the same office and used it as a delay line...but that is just a rumor, we're sure he never did anything remotely illegal with the device and used it for music educational purposes only).

Once again many thanks. It is really this with some great upgrades that I did not think about the rate is great.
I promise I will not ask for anything else this week (oh! it´s friday)

Sorry I couldn´t resist: one more question pleease... On the "alarm alternating freq only" patch if I want to put a three tone alarm (3 frequencies) where should I add them?
Thanks for the info on Sherwin
